WILLIAM J". LEACI-I, OF BURLINGTON; WISCONSIN.

SLEEVE TWISTER.

Application filed March 6, 192-8. Serial No. 92,911.

My invention relates to improvements in sleeve twisters, and it consists in the combinations, constructions, and arrangements herein described and claimed.

This application is a continuation in part of my co-pending application, Serial No. 1-i,3 i2, filed March 9, 1925.

An object of my invention is to provide a sleeve twister which is designed so as to employ dies of various sizes, whereby the dies may be used to twist tubes of different diameters.

A further object of my invention is to provide a device of the type described in which the dies are identical in construction and interchangeable.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accom panying drawings, forming part of this application, in which Figure 1 is a front elevation of the device,

Figure 2 is a section along the line 22 of Figure 1,

Figure 3 is vice, showing therein, and

Figure 4 is a diagrammatic view of the device applied to a tube.

In carrying out my invention, I provide a tube twister B having a body portion consisting of sections 1 and 2. The section 1 is provided with an integral arm 3 projecting outwardly therefrom, and having a tapering core 4. and a threaded opening 5 therein. A handle 6 having a threaded shank 7 thereon is adapted to be received within the arm 3. The section 2 is provided with an integral arm 8 having a tapering core 9, and a threaded opening 10 in the end thereof. handle 11 having a threaded shank 12 is adapted to be received in the arm 8. The section 1. is pivotally secured to the section 2 at 1-3. The section 1 has an integral tongue 14 projecting outwardly therefrom. A yoke 15 carrying a set screw 16 is pivotally 'n'iounted upon the arm 8 at 17, and is adapted to swing into engagement with the tongue 14.

The sections 1 and 2 are provided with annular grooves 18 therein. A pair of dies 19 are provided with looking flanges 20 a fragmentary view of the deone of the dies belng inserted which are adapted to be received within the annular grooves 18. The dies are also provided with openings 19'. Stop pins 21 are placed within the annular groove of each section. The locking flanges 20 are cut away, as at 22, to form abutting surfaces for the stop pins 21. Springpressed balls 23 are placed one within each of the sections 1 and 2.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. When connecting cables 24 and 25 together, their ends are placed within a tube 26. The tube twister A, which is clearly defined in my co-pending application, is placed upon one end of the tube 26, and the tube twister B is placed upon the opposite end of the tube 26. Before the tube twister B is mounted upon the tube 26, it is provided with dies, such as shown in Figure l. The tube twister B is in open position, and the locking flanges 20 are aligned with the annular grooves 18, and 9y moving the dies in the direction of the arrow 27., see Figure 3, the dies may be forced past the spring-pressed balls 23 until the cutawayportions 22 strike the stop pins Either of the dies 19 may be inserted in either the section 1 or the section 2, and frictionally held in place by the spring pressed balls 23. When the dies are in place, the tube twister B is placed in the position shown in Figure 4, and the sections 1 and 2 move toward each other until the tube 26 is held. within the opening 19'. The yoke 15 is then swung into engagement with the tongue 14: and the set screw 16 moved downwardly against the tongue. The tube twister A is then held rigidly, while the tube twister B is operated. Dies having openings of any desired shape or size can be inserted into the sections 1 and 2.

I claim:

1. A device of the type described comprising a body portion composed of sections having grooves therein, a die carried by each of said sections and having locking flanges adapted to be received within the grooves, means for frictionally holding said dies in place, and stop pins for rigidly holding said dies against rotative movement with respect to said sections.

2. A device of the type described com prising a body portion composed oi sec received in said grooves, spring-pressed tions each having a groove disposed therein balls for rigidly holding said dies in place,

at substantially the center thereof, a semi and stop pins for rigidly holding said dies 10 circular die carried by each 01" said sections, against rotative movement with respect to a flange integral with the peripheral edge said sections.

of each of said dies and disposed adjacent one side thereof, said flanges adapted to be \VILLIAM J LEACH.
